SILENCING DEVICE FOR RATTLING SASH WINDOWS.

Application filed September 16, 1925. Serial No. 56,781.

This invention relates to a device for stopping the rattle and noise caused by loose sash windows.

Its object is to provide-by a very simple and cheap device a permanent remedy for this common annoyance. Also one which shall not interfere in any way with the action and use of the window sash, and which can be instantly and easily applied by any person and thereafter remain always effective.

The distress which a rattling sash will cause to a light sleeper, and to many others is common knowledge, and I am aware that there already are a variety of devices well known and available. But they are for the most part troublesome to fix, have more or less complications, and either require adjustment from time to time or definitely interfere with the sliding motion of the window. Whereas in the case of my device all these defects are eliminated, as will be seen from the following detailed and illustrated description.

In the drawings which form part of this application Fig. 1 is a front view of my device and Fig. 2 a side view, (both these figures being much enlarged beyond the actual size), Fig. 3 is a horizontal section of part of an ordinary sash window showing the position where the device is-applied.

My device consists of a small piece of resilient steel (a) specially shaped for the purpose in View.

The steel is set to a curvature as shown at (b) and is provided at each end (0) with a peculiar claw-like extremity. This is obtained by making one curvature cut into another, the ends ofthe steel tape (a) are curved as shown at (d) and intersect ng this curve is a circular incision (e). The combination thus provides at each end a pair of sharp claw-like tangs This claw-like shape is formed in the plane of the surface of the tape, but the extremity of each claw is also slightly bent inwardly of the general curvature of the steel tape, as shown at (g).

The positions where the device is inserted against the window sash are shown at The method of application and operation of my device is as follows: Compress and insert within the clearance space (h) between the face of the sash and the side of the loosely fitting guide (or stop"). Takin care that the claw points are towards the WlIldOW sash so that the device slides with it, the claws engage the wood and are so shaped as to resist the effect of lateral vibration in either direction.

Four pieces are by preference used in each sash, two on each side one near the top and the other near the bottom. They can be left permanently in position, and because of their flexibility cause no inconvenience to the Working of the sash, but on the contrary hold it in position against the opposite stop and thus prevent or minimize airdraught." v

Having thus described the general nature and objects of my invention, also the application of the same, I claim:

In a device of the type described, a piece of resilient steel tape in the form of an are but having its extremities turned inwardly of the said are, the ends of said steel tape being each formed'into a pair ofclawlike tangs.
